Original First Rule
Publication Date: March 18, 1994
Effective Date: April 18, 1994
Federal Register Citation: 59 FR 13044
Description
This final rule promulgates the U.S. Environmental Protection Agency's (EPA) program for evaluating and regulating substitutes for ozone-depleting chemicals being phased out under the stratospheric ozone protection provisions of the Clean Air Act (CAA). In section 612 of the CAA, the Agency is authorized to identify and restrict the use of substitutes for class I and II ozone-depleting substances where the Administrator has determined that other alternatives exist that reduce overall risk to human health and the environment. EPA is referring to the program that provides these determinations as the Significant New Alternatives Policy (SNAP) program. The intended effect of this final rule is to expedite movement away fromozone-depleting compounds by identifying substitutes that offer lower overall risks to human health and the environment.

Rule 18 (7 pp, 308 KB) - Fire Suppression Alternatives
Publication Date: April 29, 2013
Effective Date: May 29, 2013
Description
This notice withdraws C7 Fluoroketone from the direct final rule issued September 19, 2012. The listing of two other substitutes, Powdered Aerosols F (KSA) and Powdered Aerosol G (Dry Sprinkler Powdered Aerosol (DSPA) Fixed Generators), in that direct final rule remain in effect.
Additional Information
DSPA generators produce combustion byproducts (micron-sized dry particles and a gaseous mixture), that mix together into a uniform fire-extinguishing aerosol before being released into the protected area. The propellant components of the system generates inert gases, which function to physically extinguish the fire by the combined effects of straining the burning flame front and reducing the heat of the combustion sources. The small aerosol particles have a high surface area­to-volume ratio, which increases their ability to rapidly distribute throughout enclosed areas and to act as heat sinks.
